Transfer ALL Settings from One Phone to Another

[BazzaBoy]

I am using Aqua Mail on one phone. I have exported settings from the App to that phone and then transferred them using Dropbox to a newly installed Aqua Mail App on another phone.

While most of the general settings transferred nicely, the signatures of accounts from the first phone did not transfer with the settings to the next phone.

Is there a way of transferring all the Aqua Mail settings (down to the last detail), on to the new phone?

Thanks for help.

Could you please report which versions of Aquamail you have on each phone?
To check that, in the account view in Aquamail, go to the 3-dot menu, then "About".
